摘　　要：分析了当前小型整秆式甘蔗收获机剥叶断尾机构的基本结构与存在的问题,继而通过原理分析做出增加耙叶辊的设计改进,并通过样机试验来验证设计。结果表明:增加耙叶辊后的机构断尾率提高到82.96%,达到了目标水平,改进的设计对断尾功能的改善是有效的。获得最优的甘蔗断尾率指标为:耙叶辊转速为700r/min,剥叶辊转速为1000r/min,耙叶辊与甘蔗交错作用深度的最佳水平为60mm,剥叶辊与甘蔗交错作用深度为40mm。Aiming at the problem of theleaf-cleaning and tail-breakingmechanism of the small type sugarcane harvester,this paper first analysis the problem existing in current structure of the mechanism in theory,then bring out the improved design-raking rollers accordingly,and carried out prototype experiments to validate the designat last.The experimentresult shows that the improved design is valuable as the tail-breaking rate is improved to 83.7%with raking rollers.To obtain the best performance,the rolling speed of theraking rollers is 700 r/min,the rolling speed of the leaf-cleaning rollers is 900 r/min,the depth of the interaction between the rake blade roller and the sugarcaneis 40 mm,and the depth of the interaction between the stripping roller and the sugarcane is also 40 mm.
